Explanation of Answers:

a) Combining Sentences with "who"

• The original sentences are:
  • A doctor is a person.
  • He treats patients.
• To combine them using "who," we identify the subject (doctor) and the action (treats patients). The relative pronoun "who" replaces "he" and connects the two clauses.
• The combined sentence: A doctor is a person who treats patients.

b) Changing to Passive Voice

• The original sentence: They are building a new bridge.
• In passive voice, the subject (a new bridge) becomes the focus, and the doer (they) is optional.
• The verb "are building" becomes "is being built" (present continuous passive).
• The passive form: A new bridge is being built (by them).

c) Correct Verb Form in Conditional Sentence

• The original sentence: If I (be) you, I would not tell a lie.
• In conditional sentences (unreal situations), we use the past tense of the verb (were) instead of the present (was or am).
• The correct form: If I were you, I would not tell a lie.

Additional Notes:

• For part (a), ensure the relative pronoun correctly refers to the subject (doctor) and maintains grammatical structure.
• In passive voice (part b), the auxiliary verb (are) changes to match the new subject (bridge) and tense.
• For part (c), remember that conditional sentences with "if" often require the subjunctive mood (were instead of was).
